Jm. Taboada et al., Improvement of the hybrid moment method-physical optics method through a novel evaluation of the physical optics operator, MICROW OPT, 30(5), 2001, pp. 357-363
This paper presents an alternative procedure for the evaluation of the phys
ical optics (PO) contribution into a hybrid moment method-physical optics (
MM-PO) code. The proposed formulation includes a linear interpolation of th
e phase over large triangular subdomains for the PO regions, where the radi
ated field can be analytically determined. This allows a drastic reduction
of the computational cost, while maintaining or even improving the degree o
f accuracy. In this way, the scope of application of the MM-PO hybrid code
is enhanced to larger problems in terms of wavelength. (C) 2001 John Wiley
